Charles, I'm certainly interested. I would like to find out how may wikimedians there are in the midlands. I intend to launch an idea which is based here. At the momement I'm waiting for feedback from a number of leading wikimedians (hint yes you three), but I am unsure as to how many people are a small car ride away. So hope this idea works.
